You can find Humboldt martens, weasel-like mammals, in just two places: Oregon's Siuslaw National Forest, and the Siskiyou portion of Oregon's Rogue River-Siskiyou National Forest. That's it.
And that's why the group Cascadia Wildlands wants the marten protected under the state's Endangered Species Act.
The best estimate is 200 animals left. Nick Cady, legal director at Cascadia, expands on the details.
